Tomatoes have a ph of and water has a ph of 7. how many more times is acidic are tomatoes than water

Answer is: tomatoes is thousand (1000) times more acidic than water.

pH (tomato) = 4.00.

pH (water) = 7.00.

pH = - log[H⁺ ].

[H⁺] = 10∧ (-pH); concentration of hydrogen ions.

[H⁺] = 10⁻⁴ M = 0.0001 M; tomato.

[H⁺] = 10⁻⁷ M = 0.0000001 M; water.

[H⁺] (tomato) / [H⁺] (water) = 0.0001 M : 0.0000001 M.

[H⁺] (tomato) / [H⁺] (water) = 1000.
